3.4  INSTALLATION

  1. Install pumps according to manufacturer's written instructions.
  2. On each scrubber dump sump pump discharge, install flexible hose, swing check valve and isolation ball valve.
  3. Install pumps and arrange to provide access for maintenance.
  4. Support piping so weight of piping is not supported by pumps.
  5. Submersible Sump Pumps: Set pumps on basin, pit, or sump floor. Make direct connections to storm drainage piping. Anchor quick-disconnect systems to bottom of basins and basin sidewalls or covers. Install pumps so pump and discharge pipe disconnecting flanges make positive seals when pumps are dropped into place.
  6. Sump Pump Basins: Install basins and connect to drainage and vent piping. Brace interior of basins according to manufacturer's written instructions to prevent distortion or collapse during concrete placement. Set basin cover and fasten to basin top flange. Install cover so top surface is flush with finished floor.

  2. Install discharge pipe sizes equal to or greater than diameter of pump nozzles, and connect to storm drainage piping.
  3. Install swing check valve and gate valve on each sump pump discharge.
  4. Install electrical connections for power, controls, and devices.
  5. Electrical power and control components, wiring, and connections are specified in Division16 Sections.
  6. Ground equipment.
  7. Tighten electrical connectors and terminals according to manufacturer's published torque-tightening values. If manufacturer's torque values are not indicated, use those specified in UL486A and UL486B.

3.6  ADJUSTING

  1. Pump Controls: Set pump controls for automatic start, stop, and alarm operation as required for system application.

3.7  COMMISSIONING

  1. Final Checks before Starting: Perform the following preventive maintenance operations:
  2. Lubricate bearings.
  3. Disconnect couplings and check motors for proper direction of rotation.
  4. Verify that each pump is free to rotate by hand. Do not operate pump if it is bound or drags, until cause of trouble is determined and corrected.
  5. Verify that pump controls are correct for required application.
  6. Starting procedure for pumps with shutoff power not exceeding safe motor power is as follows:
  7. Start motors.
  8. Open discharge valves slowly.
  9. Check general mechanical operation of pumps and motors.
  10. Check alarm annunciation at Building DDC automation system.
